X-ray emitting structures in the Vela SNR: ejecta anisotropies and progenitor stellar wind residuals
Vincenzo Sapienza, Marco Miceli, Giovanni Peres +6
The Vela supernova remnant (SNR) shows several ejecta fragments protruding beyond the forward shock (shrapnel). Recent studies have revealed high Si abundance in two shrapnel (A an…
A variable corona for GRS 1915+105
Konstantinos Karpouzas, Mariano Méndez, Federico García +4
Most models of the low frequency quasi periodic oscillations (QPOs) in low-mass X-ray binaries (LMXBs) explain the dynamical properties of those QPOs. On the other hand, in recent…
Progenitors of low-mass binary black-hole mergers in the isolated binary evolution scenario
Federico García, Adolfo Simaz Bunzel, Sylvain Chaty +2
We aim to study the progenitor properties and expected rates of the two lowest-mass binary black hole (BH) mergers, GW 151226 and GW 170608, detected within the first two Advanced…
Stellar wind structures in the eclipsing binary system IGR J18027-2016
Federico A. Fogantini, Federico García, Jorge A. Combi +1
IGR J18027-2016 is an obscured high-mass X-ray binary formed by a neutron star accreting from the wind of a supergiant companion with a 4.57 day orbital period. The source sh…
A two-component Comptonisation model for the type-B QPO in MAXI J1348-630
Federico García, Mariano Méndez, Konstantinos Karpouzas +3
Spectral-timing analysis of the fast variability observed in X-rays is a powerful tool to study the physical and geometrical properties of the accretion/ejection flows in black-hol…
The Comptonising medium of the neutron star in 4U 1636-53 through its lower kilohertz Quasi-Periodic Oscillations
Konstantinos Karpouzas, Mariano Méndez, Evandro M. Ribeiro +3
Inverse Compton scattering dominates the high energy part of the spectra of neutron star (NS) low mass X-ray binaries (LMXBs). It has been proposed that inverse Compton scattering…
